There are many uses of valves - mainly controlling the flow of fluids and pressure. Some examples include regulating water for irrigation, industrial uses for controlling processes, and residential piping systems. Magnetic valves like those using the solenoid, are often used in a range of industrial processes. Whereas backflow preventers are often used in residential and commercial buildings to ensure the safety and hygiene of the water supplies. Whether you are designing a regulation system for irrigation or merely looking for a new replacement, you will be able to find whatever type of subsurface safety valve that you need. Our products vary from check valves to pressure reducing valves, ball valves, butterfly valves, thermostatic mixing valves, and a lot more.

Surface-controlled subsurface safety valves (SCSSVs) are critical components of well completions, preventing uncontrolled flow in the case of catastrophic damage to wellhead equipment. Fail-safe closure must be certain to ensure proper security of the well. However, this is not the only function in which it must be reliable—the valve must remain open to produce the well. Schlumberger surface controlled subsurface safety valves exceed all ISO 10432 and API Spec 14A requirements for pressure integrity, leakage acceptance criteria, and slam closure.

Through decades of innovation and experience, Schlumberger safety valve flapper systems are proven robust and reliable. The multizone dynamic seal technology for hydraulic actuation of subsurface safety valves is a further improvement in reliability performance when compared with traditional seal systems in the industry.

The multizone seal technology is currently available in the GeoGuard high-performance deepwater safety valves, which is validated to API Spec 14A V1 and V1-H.

A safety valve is a valve that acts as the protector of your equipment. Safety valves can prevent damage to your pressure vessels and even prevent explosions at your facility when installed in pressure vessels.

A safety valve is a type of valve that automatically actuates when the pressure of the inlet side of the valve increases to a predetermined pressure, to open the valve disc and discharge the fluid. The safety valve system is designed to be a fail-safe so that a wellbore can be isolated in the event of any system failure or damage to the surface production-control facilities.

In most cases, it is mandatory to have a means of closure for all wells capable of natural flow to the surface. The installation of a subsurface safety valve (SSSV) will provide this emergency closure capability. Safety systems may be operated on a fail-safe principle from a control panel located on the surface that was custom-built by PHC.

The SCSSV is controlled by a ¼” stainless steel control line that is attached to the outside of the well tubing string and installed when the production tubing is installed. Depending on the wellhead pressure, it may be necessary to keep as much as 10,000 psi on the control line to keep the valve open. PHC control panels feature the proven Haskel pump line that generates the required hydraulic pressure for optimal valve control.

The TSS series subsurface safety valves are tubing retrievable surface controlled subsurface safety valves. Compared with the TS series, the safety valve features super slim outer diameter design. The control line connects the valve to the surface, and the pressurization from surface on the control line controls the opening and closing of the flapper. This series of products includes self-equalizing and non-equalizing types.

As long ago as 1936, accelerated drilling of high pressure oil and gas wells in inland waters near town sites and other dangerous or isolated places required a device to protect wells from uncontrolled flow caused by accident or other damage to surface equipment. To meet this need, many types of safety valves were built and tried, most of them being of the velocity-operated type. These valves were designed to operate by increased velocity, or by the pressure differential across the valve caused by the increased velocity of flow, or by a drop in pressure to a predetermined value, caused by the rupture of some part of the well equipment on the surface. The velocity operated valve is subjected to inherent variables of flowing wells which made it difficult for average operating people to calculate and set the closing rate accurately.

While the velocity-operated valve is suitable for flowing wells producing at reduced rates, it is less suitable in areas where large volumes of flow are permitted. In wells produced at rates at or close to their potential, it is hard to predetermine spring settings to guarantee closure in an emergency.

With the rapid extension of the offshore fields into the shipping lanes of such areas as Lake Maracaibo and the Gulf of Mexico, it became apparent that a safety device should be developed which would not have the disadvantages of the velocity-operated valve.

In Venezuela, work was started on a surface controlled subsurface safety valve which would not be dependent upon the velocity off low to close the valve. As a result of this effort} the ball valve came into being. It is used in many of the oil wells in Lake Maracaibo, Venezuela.

The WellStar® tubing-retrievable safety valve is a general production, hydraulically operated, downhole TRSV. The rugged hydraulic actuator of the WellStar safety valve provides durability and isolates the internal workings from well fluids through its unique construction. The metal-to-metal (MTM) sealing integrity in the body joints and closure mechanism places it in a premium valve category while featuring an economical price. Proven through years of installations, the simple, compact design enhances the valve’s overall reliability and provides for trouble-free operation.

MCM Oil Tools Surface Safety Valve Unit is a “failsafe-closed” or “failsafe-open” hydraulically actuated gate valve used in well testing in offshore and land operations.
